UNITED STATES PATENT OFFICE.

WIRE STRETCHER.

Application led July 20, 1927, Serial No. 207,215, and in Germany June 3, 1927.

My invention relates to wire stretchers and more particularly to a stretcher for fence wires. It is an object of my invention to provide a cheap and simple device of this kind which may be operated by any unaliiiled person. To this end I provide a inet-al rod hai/'ing a cross bar at one end and preferably a hook at the other end, the wire being wound on the cross bar, and the rod being anchored on the i 'ire by the hook after having been stretched.

Various types of stretchers have been proposed but they are complicated and therefore expensive or require skilled labour for their operation. By designing a device as described these drawbacks are removed, the novel stretcher being extremely simple as to construction and operation, and cheap in proportion.

In the accompanying drawing a stretcher eiiihodyiiig my invention and the manner in which it is used, are illustrated diagraminatically by way of example.

ln the drawing,

Fig. 1 is a plan View of the stretcher,

Figs. 2, 3 and 4 illustrate various stages of winding wire on the stretcher,

Figi-5 is a. side elevation and an end elevation of the hooi; at the end of the bar. and

Fi G illustra tes an appliance for handling barbed wire.

.ieferriiig nowto the drawing, a. is a metal har. to one cnil of which is secured a cross bar haring a shorter shank c and a longer shank (l, and l) is a hook inserted in an eye at the other end of the bar. The hook is t *isterl at .its outer end so as to form a `spiral ln operation the stretcher is placed on the wi re c as shown in Fig. 1, and is then lowered and moved 'to one side as shown in Fig. 2 so that the wire is wound about the bar a. The bai' then turned upwards toward the right as shown iii Fig. 3, and the wire is now wound about the shank d. By repeated rotation of the cross bar several windings of the wire are obtained as shown in Fig. 4. 1vVhen sufficient tension has been imparted to lthe wire the spiral shaped end f of the hook b is threaded on the wire so that the stretcher f is anchored thereon and cannot become detached of its own account or be detached by animals, due to the spiral shape of the. end The hook b can be threaded n the wire as often as the bar has been turned 1%0 degrees, so that the desired tension will be attained and maintained under all conditions.

In order to prevent hurting of the hands by barbed wire and to facilitate the stretching of such Wire, a hook g as shown in Fig. 6 may be attached to the front face of the shorter shank c in which the wire is inserted before tension is applied. This facilitates the operations illustrated in Figs. 1 and 2.

In any case the stretcher is referably engaged with the wire substantial y at the cent-re of its sag.

l wis i it to be understood that I do not.

Adesire to he limited to the exact details of consti-actions shown and described for obvious modifications will occur to `a pei-son skilled in the art. A

I ciaiincw A wire stretcher comprising a handle, a cross bar at one end of said handle projecting on either side of said handle, a hook at the end of said handle which is opposite said cross bar, and another hook on said cross bar. In testimony whereof 1 aiiix my signature.
